I will be flying to Denver in late August and renting an F800GS for a 7-day, 3000-mile jaunt through CO and UT. My own ride at home in New England is an R12GS and that's what I would have rented but none were available. I am quite unfamiliar with the F800GS, and I'm kind of looking for the "Dummy's Guide to the F800GS" Looking for any known issues (and I just finished reading up on the vent line re-routing issue) oddball tools, that sort of thing. My toolkit for the R12GS, which I am bringing along, is pretty complete but very specific, and I am not sure how its contents apply to the F800GS. What about chain adjustment? What size nut on the rear axle?
